To all whom t viiaycovwem:

citizen of the United States, residing at county of vWarren, State of cleaning Spray Head, of which the following iS/a specification', accompaniedby drawings.

This invention relates to devices -for lspray-ing liquids and particularly to spray nozzles or spray heads used in the spray .ponds of condenser installations, 1n fire extinguishers, sprinklers, L lawn sprays, g and other uses in whicha uniform nnely divided' spray is desired, especially wherethe liquid. contains slime, organic growths or other impurities. c s l The primary objects of the present invendischarge opening 1n the head to be adjusted to-various predetermined degrees to vary the' capacity of the nozzle and produce fine or heavy streams as desired. Another'l object is'to permit 'at least one side of the body to be opened Wide when desired, so that the liquid, instead vof issuing in thev form of aspray, will iiow freely out of the head with a cleansing action, expelling any growth, yslime or foreign matter\which may have-@accumulated within the head;

A' further important objectl is to spray a maximum foot of pond area and to direct the spray in the most eiicient manner, so that the maximum eifect is obtained whether for cooling, aeration or other purposes.

With the above and other objects in view,

v,the invention consists of the features of construction and arrangement of the various parts of a spray nozzle substantially as erein shown and described, reference being had to the accompanying drawings forming a part hereof, in Whichj Figure 1 is a side elevation of` the improved spray head;

Figure 2- is a front view; l Figure 3 is a 'vertical longitudinal secpray head; f Figure 4 is a v1ew similar-to Figure 3 showing the movable leaf of the head in a wide open position, as when cleaning the spray head;

Figure y6 is` a slde elevation partly in'secf tion' of plurali y of spray heads operated b a common"means located at the bank'of t e Referring to thedrawin'vs, the body A of the spray head may be in the form of a holL low bulb, threadedor otherwise 'connectedto the discharge 'line B forl the liquid or other material tto be sprayed. 'The body A. is divided into two sides or sections, the internal conformation of which is designed to l l produce a tortuous passage() for theliquid or `other material,l forcedthrough the. head.

The sections include an integral stationary" side D .andan opposite movable leaf E referably pivoted to lug? E on the body as by means of a pin* The base G of the movable leaf E- is adapted to seat in a groove inwardly directed side lof t-hen body A and maintainsthe lips K and 'L of the sections' D'a'nd E, respectively inl spaced relationship during `operation of the spray head. -The lips K and L are adapted to dene a semicircular outlet or disc arge opening O centrally across an endv of the head. Suitable means areprovided for varyin the size of the outlet opening to produce e or heavy streams, as maybe deslred, preferably by effecting a swinging movement of the movable le'af Ev on its pivot F. In this instance one end of a vertical lever P is suitably secured to one end of the leafE at Q and the portion R o f the lever is pivoted on the in F. Swing-. ing movement of the lever P about the pivot pm F will cause the movable leaf E to swing vrelatively to the stationary side D, varying the size 'of the discharge opening O to an degree desired. Thel s ide 'of the .body X represented bythe movable leaf E Amay be o ened wide as shown in Figure 4, so that t e/ liquid is permitted to liow -freely out of -the openin and beneat the base of the movable leaf E as indicated at S, the lines of-low of the li uid being such as to exert a cleansing edlect, removing and expel ing any slime,l organic matter or otherl forei substance which may have collected wit in the head or on the `interior surface of the head parts.

Occasional openin of the ,movable leaf E to wide limits wil tendv to keep the spray of head always clean and prevent clogging of 1-10 a portion ofv a spray, pond having a pond.

Inthis instance a suitable operating rod U is connected to a plurality of levers' P. \-.For this purpose the levers P may be provided'with slots V, which'are enf' gaged by pins W on the rod U. Any desired',

means may be employed for moving the arm U to simultaneously and` uniformly vary the vcapacity vof theopenings O of `the plurality of spray7 heads. Such variation in capacity may vtake place gradually or in predeterfv 'mined graduated ste In this instance the variation is effected y means located" at the bank of-the spray pond,and consists of a erating 1n conjunction with the notched r'ac "Z andadapted to be moved to vary the capacity of the` openings/O of the spray heads in predetermined graduated steps, as will be understood, the notches a each representing one step. g f vc' l "In Figure 5 ofthe drawings I have illus`" trated a form of spray :head ain which boths'ections b and c are inthe form of leaves mhvahle on pivots ,dand are maintained in spaced' relationwith,A a deflector e extending'acrossthe main portion of the head. between the leaves b and 'c.
